Power

The USB Power Delivery (PD) specification defines hardware and protocols that allow bus currents as high as 5A, VBUS voltages up to 20V, more precise power management, and even the ability to reverse the flow of current so a device can provide power to a host.

PoweredUSB enables USB devices to draw more than 500mA from the cable. Targeted at point-of-sale (POS) applications. Requires a license from IBM.

Wireless USB

Options for wireless USB communications.

Media Agnostic USB

The first use for MA USB will be 1-Gbps wireless communications based on the WiGig Serial Extension (WSE) v1.2 specification from the Wi-Fi Alliance. The Wi-Fi Alliance transferred the WSE specification to the USB-IF for use in MA USB. WiGig uses unlicensed 60-GHz frequencies for short-range communications.
